Abstract

Supercapacitor has received intense interest due to its high-charge/discharge rate and high-power density. C/Fe₂O₃ layer with different C/Fe ratios were synthesized by a solution-based approach for supercapacitor application. The influence of synthesis conditions on their electrochemical performances was investigated. Cobalt was added into C/Fe₂O₃ and significant improved its performance. The optimal C/Fe₂O₃ sample gives a high specific capacitance of 85.3 F/g and the addition of Co₃O₄ further increase the capacitance of obtained C/Fe₂O₃/Co₃O₄ to 144.4 F/g at 5 A/g. This work demonstrates an efficient supercapacitor application of low-cost metal oxides and facile solution-based synthesis approach.
